Brad, we gotta get this figured out man. I've done lots of research on Dino's and I've learned that nobody has any clue, lol. Sounds like most cases are from people that started with dry rocks and people are having pretty good results with acid washes prior to use and a curing process in a dark place with lots of waterchanges. After all this time with this stuff I really don't think biopellets or new skimmers are gonna help. I think I'd be ready to move on to more drastic measures. Maybe start with a few pieces of rock and acid wash and soak and see if it comes back in a separate tank. Have you talked to Chris (Skins) about it. I know he battled this stuff for a long time, now he has a completely different tank and all the issues went away. I really don't feel this type of algae is lack of care or anything to blame on the tank owner, I feel it's a curse you start with.
